Abstract: Arsenic is one of the naturally present and widely distributed toxicants in ecosystem. It is also produced by anthropogenic activities. As it is present in water bodies mainly, it can easily enter the food chain and finally reach human body. It has very severe carcinogenic and teratogenic effects on physiological systems. Current study focuses on the effect of arsenic on reproductive system. Our electron microscopic studies clearly demonstrate this effect. Nexin-dynein regulatory complex is a component of flagellum of the mammalian spermatozoa. It is mainly involved in regulating motility of spermatozoa......

Abstract: Flood disasters, as a natural phenomenon related to human activities, occur as a result of the accumulation of several factors, such as rain, wind conditions, and upstream conditions. Natural conditions are also influenced indirectly by the increase in population, which can trigger flooding.This study aims to determine the level of knowledge and awareness of the community towards flood disasters and to examine the relationship between knowledge and community vigilance in facing flood disasters in Candikuning Village. The study uses a quantitative descriptive method with a bivariate correlation design and an ecological approach......

Key words: vigilance, flood disaster, Candikuning Village

Abstract: Background: The conversion of forest into perennial crops, particulary cocoa and rubber farms, is a phenomenon that is increasingly affecting protected areas in Ivory Coast. This situation reveal the contrast, which threatens the survival of biodiversity, this study examines the possibility of reconstituting these ecosystems from the floristic potential that is expressed in the cocoa and rubber farms. Materials and Methods: For this, 108 plots of 400 m2 each were first laid out in 54 selected cocoa farms and 54 selected rubber farms in the Indénié-Djuablin.....

Abstract: The focus of the research was to assess the diversity and composition of algae in the community mosque lake of Jahangirnagar University campus. The research was conducted between December 2021 and August 2022. In order to carry out the investigation, 72 different samples of water were analyzed. The level of diversity was evaluated using both the Shannon and Simpson diversity indices. A total of 38 genera belonging to 7 classes (Cyanophyceae, Chlorophyceae, Bacillariophyceae, Euglenophyceae, Cryptophyceae, Dinophyceae, and Xanthophyceae) were found. Chlorophyceae made up 52% of the total generic percentage composition, which was followed by Bacillariophyceae (21%) and Euglenophyceae.....

Abstract: Background: The globalization trend has narrowed the geographical distance and the world market has unified. Viet Nam's textile and garment enterprises take advantage of this opportunity to learn from experience as well as absorb the world's technological and managerial levels. These businesses have contributed promoting the country, turning it into a nation with a dynamically developing economy and attracting plenty of foreign investors to Vietnam. TNG Investment and Trading Joint Stock Company was established in 1979 with 40 years of construction, development and growth......

Abstract: Environmental degradation is on the high increase as a result of constant discharge of industrial effluent into ecosystem. One of the major industries are industries where high level concentration of heavy metal is being generated. Steel construction companies have been implicated in production of effluents with high concentration of heavy metals. It is of utmost importance to evaluate the impact of the effluent on the environment and human who depend directly or indirectly on this environment. This work focused on the investigation of different concentration of effluent on the haematological, biochemical and histopathological parameters of Rattus novegicus over a period of 30 days......

Abstract: Background: Natural resource reserves in Vietnam such as Tam Dao National Park are being managed by the state with great interest. The conflict between the conservation of land and forest resources of Tam Dao National Park and the need for land use by the people in the buffer zone is increasingly acute. Therefore, it is necessary to determine the potential of agricultural land for the proposal of sustainable land use orientation to both conserve the natural resources of the National Park and improve the living standards of the people sustainably. With that requirement, from 2021 to 2022, a study on the sustainable use of agricultural land in the buffer zone of Tam Dao National Park was carried out.......

Abstract: Plants can produce natural dyes that can be used in the textile sector, be it the stems, skins, fruits and leaves of plants. The leaves of ferns (Pteridophyta) and the bark of mangroves are types of plants that can be used in natural coloring using the ecoprint technique. This study aims to apply fern leaves to textile materials using the ecoprint technique using two methods, namely the steam method and the tap method, designing 2 fashion product models for ecoprint, the tap method and the steam method and creating ready to wear fashion products in the form of outer products. This study used an applied experimental method with a qualitative approach and descriptive research type. The subjects used in this study were ferns which can be printed directly on cloth using the ecoprint technique. as well as alum and tunjung which are used as mordant substances. Data collection techniques in this study were applied experiments......
